Answer:
<em>The correct option is D) A species that does not normally live in an area.</em>
Explanation:
Non- native species can be described as a species which do not live in a particular habitat but are introduced into the habitat due to certain reasons or causes. The introduction of non-native species might badly affect the stability of an area. The non-native species might fight with the native species for resources like food, water, shelter etc. Sometimes, the introduction of non-native species is done so that the species can feed on any other species which is not beneficial for that environment.

Explanation:
1. evolution ~ group of related organisms that share features and characteristics
genetic change in a population or species over many generations
2. lineage ~ line of descent
3. macroevolution evolution at or below the species level ~ genetic change in a population or species over many generations
4. microevolution~ the expression of a genetic trait, or what the trait looks like
5. phenotype ~ evolution above the species level
6. species continuous ~ line of descent
Answer:
D) refractory period
Explanation:
Electrical Muscle Stimulation is caused by the electrical impulses from brain that allows muscles to contract. A neurotransmitter junction between cells and neuron is presnet which cause action potential for muscle conraction.
The refractory period is the time when the cell is repolarizing. During refractory period cells re nable to repat its action and takes time to prepare the membrane for next stimulation. An action potential can't be transmitted until there is a potential across the membrane again.
Hence, refractory period is the time during which muscle is unable to respond to the stimuli.
Answer:
1. Isotonic
2. Hypotonic
3. hypertonic
4. hypotonic
5. Hypertonic
6. Hypotonic
Explanation:
Tonicity refers to the amount of the solute concentration dissolved in the solution which determines the direction of the diffusion across the semipermeable membrane.
There are three types of tonic solutions formed on the basis of solute concentration which are:
1. Isotonic solution: When the solute concentration is the same across both the sides of the semipermeable membrane. When a cell is placed in isotonic solution it remains in the same state as no movement of water is observed as in option 1.
2. Hypertonic solution: The solution which contains a high amount of solute and a low amount of water. When the cell is placed in this solution the cell shrivels as the water movement is observed from the cell to outside down the concentration gradient like in option-3 and 5.
3. Hypotonic solution: The solution which contains the low amount of solute and high amount of water, when a cell is kept in the hypotonic solution the cell swell and could become flaccid if is a plant cell as in option 2, 4 and 6.
